Northants skipper Stephen Peters says he experienced the low point of his season so far during this week's sixth consecutive County Championship loss.
The defeat by Warwickshire was their fourth loss by an innings this summer and meant they remain winless since promotion last year.
"We're hugely disappointed. It's another thumping loss really," Peters told BBC Radio Northampton.
"We've come up against another quality outfit and come a cropper again."
Northants' first-innings score of 312 against the Bears was only the second time they have surpassed 300 runs in the Championship this season.

But it was the third day at Wantage Road that proved the most difficult for Peters, as the visitors moved from 274-4 to a declaration of 602-9, and quickly reduced Northants to 53-3 before stumps.
"That was probably a low point for me this season," said the 35-year-old.
"It's very difficult when things aren't going very well, whatever you seem to try doesn't quite work.
"I'm a heart on sleeve type of character, so I find it hard to gloss over disappointments or frustrations and that was a long, frustrating day."
Northants have brief respite from the four-day game with T20 Blast matches against Warwickshire on Thursday and Lancashire on Friday, before facing the latter at Old Trafford in a Championship match on Sunday.
